Description
Technical field
The raw material that the utility model relates to the itemize saw component of the polyurethane sheet material of a kind of processing shown in figure (1) are that a kind of polyurethane raw material with different component mixes centrifugal casting again through different proportion, processes such as slaking obtain a kind of flaky material shown in figure (2), this polyurethane sheet material not only has better elastic, wearability, flexibility, when also having the stronger surperficial and more smooth body surface of surperficial adsorptivity polyurethane to contact, after tightly being adsorbed on body surface and the cutting of cutting adhesive polyurethane under the effect that does not have external force, the coincidence of two cutting parts is sticked together, and two parts of incision are sticked together again).Accessory size C ± 0.05th shown in the figure (1) controlled when centrifugal casting.The crest line of linearity 0.2, size a ± 0.2, four jiao can not have quality requirement such as canine tooth shape defective to be guaranteed by the itemize cutting machine up and down.
Background technology
The horizontal manual itemize cutting machine of existing itemize cutting machine shown in figure (3).Its operation principle is: polyurethane sheet material (1) is placed on the flat board (13), for preventing sheet material under the gravity effect (1) and the dull and stereotyped adsorption phenomena that takes place, on flat board, be processed with a large amount of pore (12), when promoting sheet material (1) when moving right, the compressed air that blows out in the pore (12) can be with (1) thrust to the right of polyurethane sheet material.Promote polyurethane sheet material (1) and arrive limited block (11) location.Stiff end clamp (2) mobile terminal clamp (7) clamps polyurethane sheet material (1) under the effect of cylinder (4) and cylinder (6) respectively.Movable block (8) drives mobile terminal clamp (7) under the effect of tension cylinder (9) then, limited block (11) moves right together to stop screw (10), spur cutting blade (3) then along guide rail (5) fast moving, the polyurethane sheet material is carried out cutting and separating.After the cutting, all cylinder returns, clamp unclamps, and has cut apart good polyurethane bar from middle taking-up of two clamps then, retracts polyurethane sheet material to be cut (1) left, with cutting blade (3) pushed home, finishes a working cycles like this.Repeat above process, can finish the cutting of second and third bar such as polyurethane such as grade.
There is following defective in the manual itemize cutting machine of horizontal shown in the figure (3):
1. because polyurethane sheet material (1) has adsorptivity, flexibility, when horizontal positioned polyurethane sheet material, it also is difficult under the aerostatic buoyancy effect that promotion polyurethane sheet material moves having.Especially when polyurethane sheet thickness size C≤1mm, these promote more to be difficult to realize, so it is not suitable for the feeding requirement than thin material, more can't self-feeding.
2. polyurethane sheet material (1) must be delivered to limited block (11) at every turn and locate the location, otherwise width of the workpiece size will can not get control, but because limited block (11) need block polyurethane sheet material (1) location, make the cutting of feeding to the right continuously of polyurethane sheet material, whenever cutting a polyurethane must take out immediately, could cut next bar.
3. because polyurethane is an elastomer, do not produce canine tooth for guaranteeing four corner angle of part after the cutting, must be when blade (3) cutting polyurethane sheet material (1), there is the tensile force f of a level in the zone that is cut.Shown in figure (4): owing to be the effect that directly is connected between cylinder and the clamp, the power that clamps polyurethane sheet material (1) is subjected to the influence of the cylinder diameter pressure of cylinder, when pressure P was not enough, the clamping position between polyurethane sheet material and clamp (2), (7) (S, t zone) can produce slip when tension.Make work cutting edge linearity 0.2 and width dimensions a after the cutting overproof.
4. the polyurethane sheet material is evened up when guaranteeing cutting, and mobile terminal clamp (7) clamps to be held polyurethane (1) certain width t must be arranged, if the width dimensions a of workpiece less than 5mm, this way almost can't realize.
5. because the distance that movable block (8) moves on machine is limited, and the width a of workpiece is by adjusting movable block (8), make relatively distance decision between the cutting blade (3) of limited block (11), therefore the full-size of workpiece size a is restricted, and in order to obtain a size accurately, it is very difficult to adjust movable block (8), is actually by the trial cut method and obtains size a.
6. because the polyurethane sheet material is very soft, when promoting polyurethane sheet material location, the horizontal impulse that the polyurethane sheet material is subjected to is unbalanced at different positions, when limited block (11) blocks polyurethane sheet material (1), polyurethane can upwards occur bending and deformation, this distortion all is not to wait when each location, the polyurethane sheet material is clamped even up after, this distortion can cause workpiece size a and linearity to have bigger sum of errors to know to tire out error.
7. because there is adsorptivity on the polyurethane surface, after the each clamped cutting of polyurethane sheet material (1), bonding very firm between the clamping area of clamping region polyurethane sheet material (1) and clamp (2), (7), take off the workpiece that has cut and promote the polyurethane sheet material once more all very difficult.
In sum, the manual itemize cutting machine of horizontal has following several respects deficiency:
(1) can't realize automatic cutting, production efficiency is low; (2) various factors causes mismachining tolerance big, can not satisfy the required precision of product; (3) range of work is not limit, thickness≤1.0mm, width＜5.0mm and＞50mm can not cut; (4) debugging, inconvenient operation.
